Underwater acoustic networks have the potential to support a wide variety of applications from facilitating communication between autonomous underwater vehicles to supporting the remote monitoring of underwater mining equipment or environmental conditions [1]. Even though underwater acoustics has been studied for many years, and communications technologies exist for underwater scenarios, intere...

history of underwater diving dates back to antiquity. breath-hold technique in diving was known to the ancient nations. however, deep diving progressed only in the early decades of the 19 th century as the result of advancements in efficient underwater technologies which subsequently led to invention of sophisticated sets of scuba diving in the 20 th century. currently, diving is performed for ...

Multiple-input–multiple-output (MIMO) communication systems utilize multiple transmitters to send different pieces of information in parallel. This offers a promising way communicate at high data rate over bandwidth-limited underwater acoustic channels. However, MIMO not only suffers from serious inter-symbol interference, but also critical co-channel interference (CoI), both which degrade the ...
